' The Schedule referred to in these Letters Patent and making part. of tho saine.

To allfpcrsons.12o-whom these presents shall come Beit known that I, Hman B. Turrr, of Boston,

. countyoff Suffolk and State of Massachusetts, have The principle of theinvention-is ina disposition of mechanism between the locking-devices andthe han- Ydie for throwing the bolts, to be actuated by the lock,

to make a connection between the bolt-handle and thc bolts before they-can be thrown or operated by IThis inventionconsistsain the combination and construction of certain parts with a lever, pivoted to the bolts, either one or more, and movi-ng therewith, and connected with the locking-devices' to be actuated thereby in such a manner as to `establish a connection through the said lever and parts', and the handle 'for throwing the bolts so that, by then vturning the handie in theproper direction, thebolts can be thrown either in or out, asthe case may be.

In the accompanying drawing myimprovement-s in bolt-connections for locks are illustrated.

l which, by hinges, a door, B, is hung, for being opened and closed.= A

' C, abox or case, applied to inside of door; the back` plate tot this boxis shown as removed, exposing vthe interior to view. l A

D, a-series of rotating tumblers or disks, arranged within the vboli C, andconnectcd with thc spindle yto kneb or handleE, having graduated dial on outside of door, by and through which such tumblers are brought into the proper position v:to allow the -connection 'shown .two horizontal arms Q, audit, extending partially Ythe same. 1n Plate 1, Figure v"1 is a view, in elcvation,of ai; 4locking mechanism, bolts, and of connecting devices at F, with thc latch-lever F2, to be made, so that, then properly turning the handle, the 4block G will be swung on its pivot or center a.

'lhe arrangement of rotating tumblcrs 1 with the latch-lever and block, just above referred to, is 4substantially the same as that of the well-knownf- Sai-- geant Combination-Lock, and thc said several parts, in the setting and upsetting of thc'tumblcrs, &c'., operate similar thereto, and therefore it is Ilot deemed necessary to herein more particularly describe them, they forming in themselves no part of this invention.

H, a stem hung to block G ofthe Sai-geant lock, so that, in thc movement of the said block through the latch-piccellf, as described, said stem will have :a

motion into and out from, as the case may be, the axis`r of the tumbler-s. n. v

This stem II projects through one cud of the lock44 case C, and has a nut, I, in its cxtreme outer eind.

K, a lever, hung upon a fulcrum, at b, of astandard,

L, secured by screws to the lower bolt M of two bolts M M, arranged in parallel horizontal planes, one above and the other below thc lock-case, and to move in and,

through parallel vertical inside of the door. f n l i The two bolts M M are connected by a'vtie-platefOf7 so as to .nieve together. l f

rlhe lever K, above referred to, is constructed withjl an upright arm, I), made at its extreliie outer end of a hook-torni, c, partially encircling the stem H,.and'l`of guide-rails N, attached to thev along the length of the lower bolt M, and `inst above IThe horizontal arm lt to lever K has, neat-its outer end, a standard, S, to which is iixed a horizontal arm, T, projecting Aby its length across the periphery of a series of rotating tnmblcrs 'or disks U, arranged. at and upony the spindle and shaft -Vof the handle XV, provided for throwing'the bolts M.y

These tumblers are located behind the plate X, be. tween it and thc. inside of the door, and cach tumbler is in itseliconstructcd with a notch r opening, Y, into its periphery, and in other respects VSimilar to the rotating tumblers o f combination-locks, andare `stt and unset tln'ougl1.thc bolt-handle XV, withi't-s graduated dials, in a similarl manner lto the Sergeant yo r other combination-locks. .f y

.lhrough `the level' K, above referred to as hung to the bolts, connection must be established between the thrownbythc handle. v n Y V To do this,v it is necessary-to set the rotating tumblers, connected' with bolt-handle, so as to have thi; opening or notches Y thereto opposite andin position, as shown at Z, iig. ljust above the standard S co le-| ver K,land also to set the rotating tumblers 'of the cries of the tnmblers on bolt-handle into the notches' Y, which thus establishes a connection between the' bolts and the bolt-handle, so that, in then turning the bolt-handle, the bolts will be thrown, moving together and as one, and either inL or ont, as the case may be.

Throwing oli' the lorek-latch piece, by turning the lock-handle in the proper direction, the lever K is leftl free, and, by the action of thebent spring A, is moved out Vof .connection with the tumblers of bolt-handle,

so that, with their combination destroyed, it is, as is obvious, impossible to make a connection of the bolthandle with the bolts,even should the loek-tumblers be properly'set, as in such case the standard S to connection-lever K, if the lock-handle be turned to move the same, would abut against the periphcries of the tumblers, establishing no connection.

The upper part B? of the vertical arm to connection-lever K is hinged or pivoted to the main portion, which is -extendedat d, along. the part B2, forming a bearing therefor on one side. The object of this construction is to prevent injury to the locking mechanism as the bolts are operated, said hinged part B2, when the connection-lever K is moved by the action of the bolt-handle to draw in the bolts, yielding or giving to the force thereof against a fixed collar or nut, C", on the stem connected with locking-devices, thus obviating concussion or jar to the inside of the lock.

h2 a vertical lever, hung up on a fulcrum at j, of

the door, from which it extends upward and downward.

connecting with the nut C2 to stem H by its forked upper end, and by itsA lower end to and with a slide-bar,

Y2, that is -slotted at its end,A where hung'by pins l to the said lever, and at its other end is arranged to slide within the seat or rest Wl, fixed to the door in position to support the connection-lever K ata point just below the bolt-tumblers. i

With this lever-connection between the slide-bar, as the stem is actuated to throw the connection-lever K into connection with the holt-handle, said slide-bar, at the proper time, through the movement of the said stem, and just previous to the completion of its full movement, is slid on the rest, bringing its tongue-piece g just beyond the edge b of' rest, and into positon to serve as a rest and hearing to the tail-piece i of connection-lever K, Aas in the turning of the bolt-handle the bolts are thrown from time'to time.

.1, In lieu of arranging the bolt-tumblers directly on the spindle to bolt-handle, they may be on an independent spindle, and a connection between the two spindles made through gearing; and, also, itis obvious that the action and movement of the connection-1ever K is -not dependent on the use of tnmblers to bolt-handle, but with tumblers, located to be set by the bolt-handle, as described, double security is obtained, and the throwing of the bolts rendered, to the uninitiated, the more complex and embarassing.

' Various forms of locks for operating the connectionlever may be employed, and eithei` ofthe class known as combination-locks, or of any other class, and, in fact, with a locking mechanismattached to or connected with the holt-handle, for operation substantially as described, it is not absolutely necessary, although it is preferable, to have locking devices for actuating the connection-lever K or its equivalent -Having described my invention,

What I claim` and desire to secure by Letters Patent, is-

1. Thev lever K, pivoted to bolt M, in combina-tion- I with the stein H and the lock-handle, the bolt-handie, and their locking-tumblers, substantially as and for the purpose described.

2. The armedlever K, formed with tail-pieces' and hinged part B2, in combination with the slide Y2 and stem H, substantially as and for the purpose described. 3. The stem H, provided with nuts I C2, in combination with the hinged part B2 of the lever K and with the level' Z2, both Iplaying on the stem between the nuts, and operating, in combination with the slide Y", substantially as described.'

4. The slide Y2, having at one end the tongue-piece h,and moving on the rest W2, in combination ,with the lever K, formed with tail-piece i, and with the pivoted lever Z2 hinged at the other end, substantially as and for the purpose described.
